Check content before you publish.

Check whether a draft looks AI-written, review matching sources and save the result. Nota gives editors and content teams a clearer starting point for reviewing a piece.

Check for AI →How it works
01

Check the draft

Paste text or upload a file and get a result in plain English. Long documents may be checked only in part; review the result’s limits before drawing conclusions.

02

Look closer when needed

Use source matching to review overlap with selected web and scholarly sources. Ask the writer about drafts, citations or tools used when you need more information.

03

Keep a useful report

Download and share the result from your paid plan. The report connects the AI check and its limitations with a fingerprint of the text reviewed.

Tools for your review.

Batch checks

Individual supports up to 10 files per batch. Professional supports up to 100, with a separate result for each draft.

Source matching

Paid plans include source checks in beta. Matching passages show overlap; they do not prove copying or identify the first author of a passage.

Developer API

Professional includes Bearer keys and usage tracking. The API returns the model result and available limitations so you can include them in your own workflow.

Optional writing history

Writers can attach a free report of the available document history or file metadata and declare how they used AI. Treat these as additional information, not proof of authorship.

Questions about Nota

Learn more about how it works.

Can an AI check decide whether to accept a draft?It should be one part of your review. AI detectors can make mistakes, and their results do not establish whether a writer followed your policy. Check the work, sources and explanation before making a decision.
How is submitted text handled?Text is sent to the services needed to run the checks, and source checks temporarily store text while processing. You choose whether to include the text in a saved report. The privacy policy explains the details.
What does the API return?A structured result with the score, band, model version, word count and limitations. Measured error rates are included when available for the text length. Professional includes API access; Developer offers prepaid credits.
Can our writers share writing history?Yes. Writing history reports are available free. What a report contains depends on the history or metadata available; a DOCX file’s properties are more limited than a revision history. Writers can add their own AI-use declaration.
Can a team share one quota?Team seats and shared quotas are not available yet. Contact us about your requirements before purchasing for a team.
